Bootmgr.exe Missing... Mpio.sys Missing Or Corrupted. Unable To Boot?

Oct 28, 2011

I just got a computer for free, a Dell Studio 1555. When I got it, it would try to boot, then come to a screen that said that bootmgr.exe was missing. Sometimes I got a message that said something like mpio.sys was corrupted or missing. I have a Win 7 disk, so I put it in and tried to repair the installation. Each time I ran it, it said that the repair had failed. I tried to reinstall windows 7, and It made it to the first restart in the process. It showed the "Starting Windows" screen, but the colors of the windows logo never appeared, then I got the missing bootmgr screen. I decided to install Ubuntu and see if that worked, and it did (I installed it alongside the Windows installation). It was Ubuntu 10.04. I thought, "OK, so i'll just use this as a Linux machine"...and I decided to go back and reinstall so that I could use the entire hard drive. It never worked correctly again. Each subsequent time that I installed Ubuntu, I was told something along the lines of "Gnome Power Manager did not install correctly" and got a slow and choppy Ubuntu installation.Tried to install 11.10, and it failed completely. I opened the Ubuntu live from my usb drive, and opened the disk utility. I now cannot format, reformat, partition, or delete partitions on the drive. Is all of this just a case of a hard drive on its last legs, or is there something else going on here?

Attempted to export and delete the BCD.The command bcdedit /export C:BCD_Backup returned:The store export operation has failed.The requested system device cannot be found.Method 3: When I attempt a system restore, it errors with: To use System Restore, you must specify which Windows installation to restore.When I view the System Recovery Options dialog box, no Windows installation drives are listed.In addition, when I view the C: drive in the DOS window (my Windows installation drive), that drive lists as empty.

I have tried reinstalling my windows 7 onto my SSD and am having no luck. I believe I have went through most guides / troubleshooting I could find on this website as well as others. After attempting to use my original cd with no luck, I followed the steps only to have the cd go no further than 73% of the step after "copying windows files". I then burnt / mounted, whatever you'd like to call it (properly) my Win 7 to my Thumb drive and at first windows said BOOTGR is missing.

So than I read to put in the cd, repair it using a command prompt "bootrec /fixboot" which it replied successful. After which I reinserted the flash-drive only to get the same error. I have tried partitioning, "clean all" (not in that order), multiple cds, thumb drives, my friends window 7 cd for giggles to see if I would have any luck, removing a stick of ram, all usb items but the kb/m. Desperate after literally 8 hours of working on this I tried my old copy of windows xp which gave me a blue screen of sorts.

I have Windows 7 installed on my laptop.I want to use some games for Windows xp.But i tried windows xp mode and it want work becouse i have low memory just 1gb in my windows 7 then in windows xp mode i have just 256 mb. And i want to install windows xp in dual boot with windows 7 but when i start windows xp it says program is blocked due compatibility issues?While i dont have cd drive on my Viewsonic laptop i use usb flash drive.When i try to boot windows xp or other software from my usb flash drive it saysbootmgr is missing and it cant boot.Please help with that issue also i tried to use startup reapir and recovery disk from my usb flash drive but it want boot recovery disk also?

Last night I tried to absorb a 3gb partition. Tried to shrink, delete... couldn't get it back into c:, so I just made it back into a partition, different letter. I left the disk manager open when I put the computer to sleepAlienware M11x r2.Turned it on this morning, got the bootmgr missing. I dug out the original microsoft disk, plugged in my external firwire cd drive, and tried to boot from there.The setup utility showed the cd drive after I plugged it in, but choosing it doesn't seem to stick. Then rebooting doesn't behave differently. Trying to reboot from network works, says cable not connected.

I have a HP DV9000 Laptop that was originally on Vista. It playing up so I bought a genuine version of Windows 7 to install.. I have put the CD/DVD ROM to boot 1st in BIOS and have saved the changes several times but nothing seems to work??

Also when I press F9 on boot it comes up with Change Boot order and the only option it gives me is.. 4. Netbook Hard Drive?

I partitioned my HD in attempt to dual boot linux. But with a botched install of linux, I am now getting the above error when I try to boot back into windows. I have booted from an install dvd, gone to the command prompt and ran these commands I found in another thread.

bootrec /fixmbrbootrec /fixbootbootrec /rebuildbcd

All three commands were completed successfully but in the end, still no go. Any other suggestions I could try?

Recently I have had a load of hardware issues which have caused me to replace my PSU and GPU. After doing so to more powerful units, I went to boot up again and got the error: "BOOTMGR is missing"

I have had this before when I remove my secondary HDD and just try and boot from my primary SSD, but after re-connecting the secondary HDD it would work again (telling me this BOOTMGR is on the HDD, even though the Windows files are on the SSD).

I don't know what to make of this as if I boot from the SSD alone nothing happens and it restarts, and if I connect the HDD and it boots then it goes into the System Recovery and after repairing/restoring still won't work. I think the BIOS settings are correct, with the SATA drives set to AHCI (as I'm 99% sure they were before).

I wiped my HDD clean with the Ultimate Boot CD and the DBAN application. I formatted a USB device to NTFS and extracted a Windows 7 ISO to it. After I wiped the HDD with DBAN, I formatted the HDD with GParted to NTFS. Now, when I try to Boot the laptop with the USB that has the extracted version of Windows 7, it is telling me that the bootmgr is misssing, when it is on there! I tried buring the ISO to a dvd, but then I got he fabulous stop error message basically telling me that I have bad media (bad DVD). I even tried using an external HDD with the extracted Windows 7 ISO on it and got the same bootmgr is missing error.

I checked OS drive in partition wizard bootable , it is intact..Windows installation is there....Every drive is ok but somehow booting not from that drive.I will attach photographs of Partition Wizard Partiton status.

Earlier in the day i tried to install a MacOSX (I've formated the second hard-drive asoff now) on a seperate hard-drive (CRIVE AKA Windows 7 drive was unplugged). After i was done i decided to plug in the c drive because i wanted to get on windows to setup dualboot. But for some reason it said bootmgr missing...

I've tried bootrec /fixboot and the other ones.

I just checked my drive somehow Cdrive turned in to D drive would that be the problem? Could somebody please show me a way to change from D drive to C drive?

If this would help nail the problem. Also tried to boot the hard-drive from my laptop via esata. I get a different problem i get a blue screen during the Windows seven loading screen. Heres the stop code: 0x0000007b.

Basically what originally happened was that I tried installing windows 7 off of my hard drive and during the "completing installation" phase the computer lost power and was shut down. Turning the computer back on iIhad a screen which said something of the likes of set up is starting. From then on I was in a infinite boot loop where it would give me a set up screen and restart. I desperately needed to backup my files which I did not bother to do so.

I used my secondary desktop running vista, plugged in my other hard drive and backed up all my files successfully. I thought I would format the disk since I was done backing up all my data and I would go right on ahead and install a fresh windows 7 via the CD. I go into bios and set the windows CD to boot and I unplug my vista hard drive and leave only the formatted 1TB HD plugged in. And now I get the "BOOTMGR is missing" error. As I have read it's due to deleting everything off the hard drive including the...bootmanager.

Now with the tools that I hold (mobo with bios access, windows 7 installation CD, another hard drive with Vista). How shall I go about getting my hard drive ready to install a fresh copy of windows 7. I have the retail cd, I have another HD with vista if needed, and I have the clean hard drive which i would wish to install windows 7. I set my bios to boot via the CD first and put in the disc and let it work it's magic, I would like to point out that it still gives me a BOOTMGR error. It asks me to press a key to load from the CD and then I get the error that I know is coming.

I have a hp G71-449WM Notebook running Windows7 premium 64bit. I can't boot computer the repair disc I have doesn't seem to work. I have no installation disc to fall back on and I can not seem to get it to boot in safe mode. Right now its asking me to find the needed driver in the driver folders. Unless it's called something else I do not see a bootmgr driver. Right now its asking me to connect to the network which would be cool but i don't know what folder they where asking me to type in.

So I tried installing Windows on my new machine and did waht seemed to be the recommended thing and plugged in only my SSD into the Sata port, leaving my other drives unplugged until after the installation. Everything went fine and I was able to get Windows 7 up, drivers were installing and everything was peachy, but Then I plugged in my other drives, and when I did so with the computer running Windows immediately recognized them and I could access them, as well as do whatever I wanted. However when I restarted I got the message BOOTMGR is missing.

Now, you may be thinking that this is a simple issue of it trying to load from one of those other HDDs, just set the boot order in the BIOS blah blah. But its not. I set the boot order in the BIOS to use the SSD, I set the SSD to the top of the list within the HDDS priority order and still nothing. I then took it a step further and instead of selecting the order manually told it to boot from the SSD flat out, boot from this drive and the same error message came up. I already did the boot from Windows disc, startup repair thing - didn't work.

I have just installed a new P5G41T-M LX Series motherboard and two DDR3 x 2GB replacing DDR2. During startup a message says BOOTMGR is missing, press Ctrl Alt Delete to restart, on restart the same message is repeated.

I was trying to reclaim some unallocated space on the drive and in the process seem to have lost boot manager, so it won't load Windows. If I put the disc in, it's not able to automatically able to repair because it says the repair disc I'm using is not compatible with the OS I have installed. This is the same disc I used to install Win 7 in the first place. Tried using cmd prompt to reload boot manager manually,and it completes the operation successfully but still says bootmgr is missing at start up.What's scaring me is that if I try to just install Win 7 again (onto the unallocated space), the hard drive just turns off and the hdd light comes on solid. This is when I choose 'Install Now' from the opening screen before selecting partitions etc. I'm typing this post from a spare hdd. The only thing I can think off at this point is the get an enclosure and recover my files; then wipe the hdd in question and reinstall Win 7.

I have a brand new Sony SVT13112FXS - hard drive is a hybrid of 500 GB HDD and 32 GB SDD.I was attempting to reformat it to get all of the anti-virus stuff off, except when I tried to reformat no disks were shown in the reformat tool. It asked for drivers, so I assumed I'd need to install the SATA/chipset drivers. I downloaded them from the Sony website but it wouldn't allow me to install them (from a flash drive). Specifically the error is "No drives were found. Click load driver to provide a mass storage driver for installation."In my troubleshooting I (stupidly) marked the wrong partition as active and got the dreaded "bootmgr is missing" upon restart. I attempted to repair using the windows 7 disk as a recovery tool and selected "startup repair" 3 times, but it still does not work.I am able to get into command prompt and I am assuming I can inactivate the (wrong) active partition there. However, when I go into DISKPART and type "list disk", all that shows up is my flash drive that I am attempting to install windows from - the computers hard drive does NOT show up here.I will also happily completely reformat instead of repairing, but I cannot do that since I can't get the disks to show up in the reformat tool.

My computer can no longer boot into windows, and i get the following message when starting up my system:

"BOOTMGR IS MISSING press ctrl+alt+del to restart."

After some googling and trying to solve my issue, I run a startup repair as i have found that to be the most common issue with this problem I have, but with no success. when I run the startup repair from the recovery disk i get the following description of why it cannot run the startup repair:

I'm getting the winload.exe missing or corrupted error, and I can't seem to find a fix for it if you have an oem computer, and thus no installation disk. I cannot go to the startup repair option (pressing f8 while on the screen), it just does nothing.

I started up my computer around an hour ago and found the following message; "The file system32/hal.dll is missing or corrupt.re-install the file." So, at a loss as I'm not a Tech-person in any yway, I turned to the internet and found, after several XP posts, some to do with Windows 7. I'm on 64-bit, and have tried inserting my installation disk as well as the system repair.I've looked at this, but seeing as I'm Windows 7 & not XP I can't see why it would work; Error Message: Windows could not start because the following file is missing or corrupt I'm following another Microsoft guide that asked to me run a command in a command prompt, Bootrec.exe which in turn gave me 4 options, only I'm not sure which option to choose.

My husband's comp crashed...he had Win7 Os. Recovery did not work! I tried to reintall Win7 got as far as formatting the hard drive. I then reinserted the cd to reinstall and now all I get as far as "Press any key..." I press a key and "BOOTMGR MISSING" press ctrl + alt + del to restart. Of course this doesn't work.I have reset the bios so that cd-rom is the only bootable device. It will not move from the bootmgr missing screen. The cd is a legal bootable copy, the hard drive and dvd player work I have tried them in another comp.System Configuration[CODE]

Her computer is an HP laptop it is runnung windows 7 . I have created the recovery disk( 32 bit) from online as that is what most sites said to do. After it said it was loading the windows files I clicked next. Then it said system recovery options.In the box it says (recovered) 292135 MB (d Local Disk. It is checked on use recovery tool taht can help fix problems starting windows. I click next. I get a pop up that says this version of system recovery options is not compatible with the version of windows you are trying to repair,So then I made the 64 bit recovery disk & restarted. I was unsure if it was 64 bit or 32 bit to start.

First off, why is reinstalling windows 7 such a pita? I've done it several times and it's soooooooo bad. With that aside, tonight I was attempting to reinstall 64 bit from 32 bit. I reformatted my hd using dos because advanced recovery simple does not work. After formatting and restarting I'm getting te bootmgr error. After reading countless threads with fixes nothing is helping. I CANNOT get past this error. I have the disc in, it won't go past the error. Pushing f2, f8, and f12 does not work. I can't do anything in the bios. Most of the solutions simply assume you can get PAST the error.

The next step I tried was unplugging the hd I formatted and installing to a different hd. This gives me an error of missing a device required. At this point I have no idea what to do besides maybe reformatting the hd again using another pc. Is there a recovery program I should dl to a blank cd?

i make the partition as active by going to computer managment-> disk management got this popup message, Only make a partition as active if it contains a functioning operating system. If the partition lacks an operating system. marking it active might cause your computer to stop working. Do you want to continue?

I have a very big problem with my reinstall of Windows 7 Pro. I have now lost the bootmgr and am not able to "see" my SSD. Ouch! I searched the forum for my error: 0x800704f and couldn't find it nor could I get to see my SSD and am therefore not able to use the tutorial to "get it back." Well, I am at a loss at this point. I was originally trying a fresh install of Windows 7 pro. But, just prior, I got an error box that the Catalyst Control Center was not working properly(or something like that). But, when after all my efforts seemed to take me further down the rabbit hole. I concluded that I must post this thread!I built it myself and know just enough to make me dangerous!

i had an unexpected shutdown, i tried to reinstall the windows 7 as it wasnt working. i formated the partition that the operating system was on, but then was unable to install the new OS.

it wont let me delete partitions or create new ones.now everytime i start the computer it is missing bootmgr.ive tried unclicking the hard drive cables which gets me into the repairing windows bit. but this doesnt help as i deleted the OS.

with bootmgr is missin i have two partitaion one has windows 7 64x and other windows xp sp3 32bit. I can only go to windows xp (i am in it atm) if i choose windows 7 it say error BOOTMGR is missing . I am very newbie at this stuf
